Title: Refrigeration arrangement for extremely low temperature
Inventor: KO NAOKI
IPC: F25B9/14
Filed: 1990-09-12
Abstract: PURPOSE:To increase the refrigeration efficiency of the title arrangement, by a method wherein a plurality of extremely low temperature refrigeration machines are provided, each of them does the action of compression-andexpansion in reverse timing with each other, and each small container storing a metal hydride separately communicates with a pulse tube of each of the extremely low temperature refrigeration machines and is connected to each heat exchanger through each of the pulse tubes. CONSTITUTION:Since each of refrigeration machines 7, 8 does the action of compression-and-expansion in reverse timing with each other, each of metal hydrides 27, 28 also comes to absorb and radiate heat in the reverse timing with each other. That is to say, since these metal hydrides 27, 28 absorb and radiate heat each other through small containers 25, 26, the heat exchange efficiency of these metal hydrides 27, 28 is heightened and a time for absorbing and radiating the heat is shortened, and thus by the amount of the time shortened, the frequency of the compression-and- expansion of each of the extremely low temperature refrigeration compressors 7, 8 is heightened. For that reason, the refrigeration efficiency of the title arrangement is more increased.

Abstract: PURPOSE:To release a player from the troublesome of relocating lent balls by providing a lent ball release means corresponding to each pachinko (Japanese vertical pinball) machine and discharging the lent ball directly to a hit ball supply plate with the lent ball guided to a prize ball discharge trough of each pachinko machine. CONSTITUTION:In order to obtain a lent ball by using a coin by a player, first a right side input port 3R is charged with the coin. By the charge of this coin, a computer judges the lent ball to be released to a right side pachinko (Japanese vertical pinball) machine 1. Whether the coin is true or not is confirmed by a coin sorter, and in the case of discriminating the coin unsuitable, the coin is returned from a change return port 8. On the other hand, in the case of discriminating the coin proper, a number of the lent balls corresponding to an amount of the coin is calculated by a computer with a signal of this lent ball number transmitted to a lent ball release means 10. By receiving this signal, a driving part 13 of the lent ball release means 10 is actuated to release the pachinko balls of the lent ball number to a pipe 16 from a supply passage 11. This pachinko ball, which passes through the pipe 16, is guided to a prize ball discharge trough 1a and directly discharged as the lent ball to a hit ball supply plate 1e. Accordingly, a game can be immediately started by the player with no necessity for relocating the lent ball.

Abstract: PURPOSE:To obtain a single-crystal silicon layer without forming and fusing steps for a thick polycrystalline silicon layer by forming an insulating film having good wettability with fused silicon on a silicon substrate, opening holes at parts of the film, thereafter supplying fused silicon on the insulating film containing the opening parts, and cooling and solidifying the silicon. CONSTITUTION:On the surface of a silicon substrate 11, a silicon oxide film 12 and, e.g. a silicon nitride film 13 whose contact angle with fused silicon is small, are sequentially formed. Then, parts of the oxide film 12 and the nitride film 13 are removed by etching, and opening parts 14 are provided. Then, the temperature of the substrate 11 is kept at a value slightly lower than the melting point of silicon. The fused silicon is supplied thereon and deposited on the entire surface of the substrate. Since the heat conducting coefficient of the silicon oxide film is small, the fused silicon supplied thereon is hard to be cooled than on the upper parts of the opening parts 14. With the opening parts 14 as a seed, the crystal grows, and a single-crystal silicon layer 15 is formed on the substrate 11. Then, the surface is polished and flattened. Thus, the SOI substrate wherein the single-crystal silicon layer 15 is formed on the oxide film 12 and the nitride film 13 other than the opening parts is obtained.
